Hi Brian,

Looks good.

Just be cautious of overlapping tubes/pipes on the surface when making boolean as I have seen some problems.

First one can be seen on simple boolean of 2 tubes at angle:-


Made boolean union, with result:-


The workaround for the above is to make the pipes different sizes (even is only by .001)



I have also seen problems due to where the seam of the pipe is in relation to the surface. I will have to find good repeatable example to show.
